A mechanical vending machine exchanging 1€-coins for Bitcoin.
It works using the easywallet.org service which provides a Bitcoin wallet with a web interface not unlike an online banking account, but much simpler. The only way to access the account is through a secret link, which is received in exchange for the 1€-coin.
Opening this link in a web browser, the costumer can instantly send this 1€ (minus material costs) to another Bitcoin user, for example Wikileaks.
